In an effort to save billions of gallons of wasted water and people’s spare time in one fell swoop, Rachio has announced its Iro Smart Sprinkler Controller that lets you manage your lawn sprinkler system from your mobile device over the internet. This single Wifi-enabled box adds brains to your otherwise dumb centralized sprinkler system, automatically adjusting to weather and seasons to use as little water as possible while also keeping the grass green and healthy.
